ONE IMPORTANT REASON Why to check Reynolds Number for Orifice Flowmeter

An Orifice Meter is basically a type of flow meter used to measure the rate of flow of Liquid or Gas, especially Steam, using the Differential Pressure Measurement principle When this Orifice Plate is placed in a line, a differential pressure is developed across the Orifice Plate. This pressure drop is linear and is in direct proportion to the flow-rate of the liquid or gas. The viscosity of a fluid is a measure of its resistance to deformation at a given rate.
